On systems without dup2(), Python tries to compile its own from Python/dup2.c, but this file refers to close() without including unistd.h. This causes it to not compile with newlib (and possibly other C libraries, presumably it was relying on fcntl.h indirectly including it?). This is probably true of all older versions as well, but Python 2.x doesn't appear to actually bother to compile dup2.c even if the system lacks dup2, so it doesn't actually cause a build error there. (building python for a semi-freestanding environment is "fun") |

(as a sidenote, the last significant changes to dup2.c date back from 1994) |

Is it sure? The file configure.in has the same command in both versions:
AC_REPLACE_FUNCS(dup2 getcwd strdup)
Added the #include anyway in r85236, r85237, 85238.
